JOHN W. BRAY, OF LEEDS, ENGLAND.

INCANDESCENT GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 7 50,018, dated January19, 1904.

Application filed July 14, 1903. Serial No. 165,506. (No model.)

To all whom it may concern:

Be it known that I, JOHN WILLIAM BRAY,

I a subject of the King of Great Britain and Irener that thegas may beconsumed more economically and a better light obtained than has hithertobeen the case. The tip being noncorrosive, the life of the burner ismaterially prolonged.

My invention furtherconsists in providing a clip which has for itsobject to prevent the mantle-rod from shaking when placed in theburner-tip.

The non-corrosive burner-tips hitherto used have been constructed'withround holes, thereby giving relatively small space for the mixture ofgas and air to pass through as compared with the area of the wallsbetween the holes, which obstruct the upward flow of the mixture of gasand air, and thereby lessen the eflficiency of the burner.

In describing my invention in detail reference is made to theaccompanying sheet of drawings, similar letters indicating similarparts, in which Figure 1 represents a plan of the burnertip. Fig. 2represents a plan of the burnertip looking from below. Fig. 3 representsa sectional elevation of the burner-tip fixed to a socket for attachingto a burner-tube and a wire-gauze diaphragm fixed immediately below thesaid tip. Figs. 4 and 5 are details of the clip hereinafter referred to.

In carrying out my invention I construct anon-corrosive tip A, ofporcelain, steatite, or similar material. The said tip A'is ofcircularform, having close to its outer edge a circle of approximatelyrectilineal holes Bthat is to say, perforations bounded by substantiallystraight lines. Immediately inside this circle is another circle ofsimilar rectilineal holes B, as shown in Figs. 1 and 2. By this means Iobtain almost the maximum of open area in the holes and the minimum ofwalls between the holes. Within the area occupied by the holes B B andon the top side of the tip A is formed a slight boss C, with a hole D asshown in Fig. 2into which is fitted a clip H, made of any suitable shapeor material, but by preference of sheet-brass made in the form of astar, having, by preference, six arms J J J J J J, with a central part Kleft blank, which blank part has a hole K through its center made forthe purpose of facilitating the removal of a broken mantle-rod. When theclip H is fixed in position, the remaining blank part prevents themantle-rod from slipping through the hole D, as shown in Fig. 4c.

Before the clip H is placed in position in the tip A each alternate armJ of the star is turned up to a vertical position, as shown in Fig. 5,thereby forming a split tube. This split tube is placed in the groovedhole D of the tip A,

so thatthearms J work in the grooves Gr and have sufiicient spring totighten around the mantle-rod, which prevents the mantle-rod fromshaking when the same is placed in position through the central hole Din the top of tip A. The three arms J of the star are wrapped over theflange F on the boss E, thereby securing the clip H to the tip A, asshown in Fig. 3.

The burner-tip A is placed in a suitable metal tube or socket L. Thesaid socket may fit into or around the top of theburner-tube.Immediately under and in contact with the said burner-tip A is placed adiaphragm M, of wire or like gauze, for the purpose of preventinglighting back.

What I claim as my invention is 1. In combination, a burner-tip having asubstantially flat face, a circle of approximately rectilinear holes insaid face, a socket D in said face, and means for holding a mantle-rodin said socket.

2. In combination with a burner-tip having a socket D, a spring-cliplocated in the socket and adapted to hold a mantle-rod, substantially asdescribed.

3. In combination a burner-tip having its central portion provided witha socket and an I inwardly-extending portion having a grooved outerface, and a rod-holding clip extending into the socket and havingspring-arms engaging said grooved edge, substantially as described.

In Witness whereof I have hereunto set my 15 hand in the presence of twoWitnesses.
